Where are the fuel injectors on a 1996 Chevy S10 blazer?

On a 1996 Chevy S10 Blazer, the fuel injectors are located on the intake manifold. They're usually positioned above the intake ports where the air/fuel mixture enters the cylinders. To be precise, you'll need to look directly down onto the top of the intake manifold. You'll see them fairly easily, as they are individual components sticking down into the intake manifold.
